首先,需要在WinForm中安装OpenTK Nuget包。
然后,可以按照以下步骤绘制一个立体小球:
1. 在WinForm中添加一个控件,例如Panel,用于显示绘制的小球。
2. 创建一个OpenTK.GLControl控件,将它添加到Panel控件中。这个控件将用于OpenGL绘制。
3. 在GLControl的Load事件中,初始化OpenGL的相关设置,例如背景色、深度缓存等:
```csharp
private void glControl_Load(object sender, EventArgs e)
{
GL.ClearColor(Color.Black);
GL.Enable(EnableCap.DepthTest);
GL.DepthFunc(DepthFunction.Lequal);
GL.Hint(HintTarget.PerspectiveCorrectionHint, HintMode.Nicest);
}
```
4. 在GLControl的Paint事件中,绘制小球。可以使用OpenTK提供的GLU库来绘制球体:
```csharp
private void glControl_Paint(object sender, PaintEventArgs e)
{
GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit);
GL.MatrixMode(MatrixMode.Modelview);
GL.LoadIdentity();
GL.Color3(Color.Red);
GL.Translate(0, 0, -6);
GL.Rotate(rotation, 0, 1, 0);
GLU.Sphere(quadric, 1.0, 16, 16);
rotation += 1f;
glControl.SwapBuffers();
}
```
5. 在GLControl的Resize事件中,设置OpenGL视口的大小:
```csharp
private void glControl_Resize(object sender, EventArgs e)
{
GL.Viewport(0, 0, glControl.Width, glControl.Height);
GL.MatrixMode(MatrixMode.Projection);
GL.LoadIdentity();
GLU.Perspective(45.0, (double)glControl.Width / (double)glControl.Height, 0.1, 100.0);
}
```
完整代码如下:
```csharp
using System;
using System.Drawing;
using System.Windows.Forms;
using OpenTK.Graphics.OpenGL;
using OpenTK.Graphics;
using OpenTK;
namespace WinForm_OpenTK_Sphere
{
public partial class Form1 : Form
{
private GLUquadric quadric;
private float rotation = 0f;
public Form1()
{
InitializeComponent();
glControl.Load += glControl_Load;
glControl.Paint += glControl_Paint;
glControl.Resize += glControl_Resize;
}
private void glControl_Load(object sender, EventArgs e)
{
quadric = GLU.NewQuadric();
GL.ClearColor(Color.Black);
GL.Enable(EnableCap.DepthTest);
GL.DepthFunc(DepthFunction.Lequal);
GL.Hint(HintTarget.PerspectiveCorrectionHint, HintMode.Nicest);
}
private void glControl_Paint(object sender, PaintEventArgs e)
{
GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit);
GL.MatrixMode(MatrixMode.Modelview);
GL.LoadIdentity();
GL.Color3(Color.Red);
GL.Translate(0, 0, -6);
GL.Rotate(rotation, 0, 1, 0);
GLU.Sphere(quadric, 1.0, 16, 16);
rotation += 1f;
glControl.SwapBuffers();
}
private void glControl_Resize(object sender, EventArgs e)
{
GL.Viewport(0, 0, glControl.Width, glControl.Height);
GL.MatrixMode(MatrixMode.Projection);
GL.LoadIdentity();
GLU.Perspective(45.0, (double)glControl.Width / (double)glControl.Height, 0.1, 100.0);
}
}
}
```
以上是简单的绘制小球的代码,可以根据需要进行修改。
